Title: Improvements relating to dyestuffs and their application
IPC: C09B67/42
Filed: 1932-05-27
Abstract: Amides of organic acids, which are sparingly or not soluble in water, but easily soluble in alcohol are used as diluents for adjusting the strength of dyes soluble in alcohol.  According to examples, p-toluene sulphamide is added as diluent to (1) auramine, (2) the azo dye from diazobenzene and the 3-methyl-5-pyrazolone obtained from 1-amino-2-chlorobenzene-5-sulphonic acid, (3) 4<1>-nitro-4-aminoazobenzene, (4) 1-amino-4-anilidoanthraquinone, (5) 3 : 6-diphenylnaphthophenosafranine 2 : 7 - disulphonic acid and (6) the unsymmetrical urea from 4-amino-4<1>-oxyazobenzene-3<1>-carboxylic acid and 4-amino-3-methoxyazo-benzene-3<1>-sulphonic acid.  Other amides which may be employed are o-toluene-sulphamide, benzenesulphamide toluene 2 : 4-disulphamide, chlorobenzene-sulphamide, toluene sulphanilide, benzene sulphomethylamide, a -naphthalene sulphamide, b -naphthalene sulphanilide, acetanilide, acetoacetanilide, stearic acid amide, palmitic acid anilide, oleic acid amide, benzamide, benzanilide, and a - or b -naphthoic anilide or amide.  Other dyes soluble in alcohol, which may be employed are unsulphonated azo-dyes, metal compounds of anthraquinone dyes, oxazines and pyronines, and the dyes of British Specifications 18729/08, [Class 2.  Acids and salts, Organic &c.], and 293,358, [Class 2 (iii), Dyes &c.], and of French Specification 634,457.  The dye referred to in example (5) is obtained by oxidizing phenyl-2-naphthylamine-5-sulphonic acid with 4-amino-2-sulphodiphenylamine, treating with bisulphite according to British Specification 14962/98, [Class 2, Acids and salts, Organic &c.], and allowing the product to react with aniline according to British Specification 14961/98, [Class 2, Acids and salts, Organic &c.].  The dye preparations obtained are useful in nitro-cellulose lacquers, spirit varnishes, and for colouring phenol-formaldehyde resins.  French Specification of Addition 31190 also is referred to.

Title: Microwave Circuit
Inventor: ROSEN HAROLD ALVIN
IPC: H03H7/48
Filed: 1967-04-03
Abstract: 1,166,402. R.F. couplings. HUGHES AIRCRAFT CO. 3 April, 1967 [14 April, 1966], No. 15165/67. Heading H4A. [Also in Division H1] The separate outputs of a number of micro - wave devices are connected to a common output by means of switches having two input ports which can be connected alternately or simultaneously to a common output port. As shown, a number of amplifiers 1, 2, 3, 4 to be operated in parallel are coupled in known fashion to a common input P i  by hybrid circuits 10, 11, 12. The outputs of the amplifiers are connected to a common output P o  by means of three switches 13, 14, 15 each having two input ports A, B which can be switched alternately or simultaneously to an output port O. This enables the outputs of the amplifiers to be combined in any fashion. Each switch comprises a Faraday device 32 producing a 45-degree clockwise or anticlockwise rotation of the orthogonally polarized inputs E A , Eg whereby one input signal is coupled to output port O and the other to a dissipative load L arranged orthogonally to the port O The output signal is selected by switch 37 which determines the direction of the axial polarizing field and hence the sense of the Faraday rotation. If no field is applied, the vector sum of the two input signals is derived at the output O. In the event of a small inequality of the input signals, the vector sum will be polarized at a small angle to the output probe and a compensatory rotation, determined by switch 37 and rheostat 38, becomes necessary.

Filed: 1936-05-29
Abstract: 462,877. Television. STANDARD TELEPHONES & CABLES, Ltd. May 29, 1936, No. 15229. Convention date, June 8, 1935. [Classes 39 (i), 40 (iii), and 40 (v)] All the points of an image, or portion of an image, are transmitted simultaneously by using a piezo-electric element of different frequency for each point. Received signals are impressed on a piezo-electric plate 1<1>, which is divided into elements having different frequencies and is so situated between two polarizing sheets 18, 19 that light from a source 21 is modulated in accordance with the vibration of the elements. The sheets may support electrodes 2<1>, 31 on each face of the crystal, and the analyzing sheet 19 may be translucent to reproduce the image. At the transmitter, each element is maintained in continuous vibration and modulates light from a view IT, which falls on a photo-electric cell 11 to produce a current of double the frequency of the element and proportional in amplitude to the intensity of the point incident on the element. The crystalline elements are in one large block, which decreases uniformly in two directions, and the two faces are sectionally divided by two sets of saw cut, at right angles, Figs. 2 and 3 (not shown). The block has electrodes supported by grids which register with the saw cuts and are associated with a common thermionic oscillator 7 or amplifier 8. The elements may be divided in groups, each of which has separate electrodes and is connected to its amplifier through an electric band-pass network, which admits the band of frequencies allocated to the group. The Specification as open to inspection under Sect. 91 comprises also a piezo-electric crystal mounted in a vacuum and covered on a surface normal to the electric axis with a photo-electric layer. Such a crystal may be kept in continuous vibration by light interrupted at its natural frequency. Transparent electrodes may be avoided by using a metallic grid. Spaces in the frequency spectrum may be used for transmitting other signals. This subject-matter does not appear in the Specification as accepted.

A mixture of liquids, e.g. oil or petrol, and water, partially or wholly emulsified and containing solid contaminants, is introduced at 24 into a housing 12 and passes inwards through pleated, resin-impregnated cellulose filters 31, solid contaminants being removed thereby. The liquids pass upwards to the interiors of coalescing units 36 comprising an inner sheet of pleated resin-impregnated cellulosic material, an intermediate sheet composed of a homogeneous mixture of dissimilar fibres and an outer sheet like the inner one. It is the intermediate sheet which performs the coalescing function, and it may comprise two or more of the following : asbestos, cellulose, (cotton, wood or viscose), glass, nylon, polyester, polyethylene and vinyl fibres. The sheet may be formed by Fourdrinier methods, felting, or bonding under heat and pressure. An aldehyde resin may be used for impregnating or bonding. Coalesced water sinks onto a dividing plate 19 while the oil or petrol passes through filters 51 differing from filters 31 only in having a coating of a silicone resin to repel any remaining water, into the uppermost zone 20, whence it is discharged through pipe 27 and valve 64. When a small amount of water has collected on the plate 19 in the zone 21 some of it will pass through pipe 70 to a diaphragm chamber 65 whereby a valve 63 is opened, and the water passes under a baffle 61 and down a tube 59 to be discharged through it. If the amount of water becomes excessive the diaphragm is further operated to close valve 64 until more water has been removed. In an alternative apparatus the filters 31 are omitted and the supporting plate 40 has a depending skirt extending to the bottom of the elements 36 ; plate 55 is omitted.
